Yes. This certainly happens. The whales are smart animals and humans are smart animals who do lots of things—particularly young humans who imperil themselves—and approaching boats, or coming into proximity of boats, is certainly a risk. As I mentioned, we're seeing substantial evidence of propeller strike wounds on whales, particularly in the northern resident community.
This is another reason, I think, that enforcement of new government regulations on marine mammal regs on approach distances to boats is so important. Keeping the boats well back from the whales so they don't become acclimated and don't learn to play with them is key.
